Obtain accurate and reproducible results in immunohistochemistry applications with Thermo Scientific™ Chromogranin A, Rabbit Monoclonal Antibody, part of a comprehensive antibody portfolio. Studies show rabbit monoclonal antibodies are more sensitive and specific than other available markers.

Chromogranin A (a protein of 439 amino acid which is encoded on chromosome 14) is present in neuroendocrine cells throughout the body, including the neuroendocrine cells of the large and small intestine, adrenal medulla and pancreatic islets. It is an excellent marker for carcinoid tumors, phenochromocytomas, paragangliomas, and other neuroendocrine tumors. Coexpression of chromogranin A and neuron specific enolase (NSE) is common in neuroendocrine neoplasms.
